Phlebotomy is the process of making an incision in a vein with a needle. The person who performs that is called as Phlebotomist.

Given below are tubes color for which test test which one is used is given clearly. They are ::

Grey-Top Tube - Potassium Oxalate. This tube is used primarily for glucose tolerance testing.

Lavender-Top Tube - EDTA: EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC. The larger (6ml) tube is used for blood bank procedures.

Red-Top Tube - This tube has no anticoagulant and is used for many chemistry tests, drug levels, and blood bank procedures.

Green-Top Tube - Sodium Heparin or Lithium Heparin

Navy Blue-Top Tube - There are two general types - one with K2 EDTA and one with no anti-coagulant. This tube is used primarily for trace metal analysis.

Serum Separator Tube (SST®) - This tube contains a clot activator and serum gel separator. It has no anticoagulant and is used for many chemistry tests. It cannot be used for certain drug levels or any blood bank procedures.

Yellow-Top Tube - ACD (Sol. A or Sol. B).

Blue-Top Tube - Sodium Citrate (NaCitrate): This tube is primarily used for coagulation studies (PT and PTT). Complete filling of this tube is essential to obtain accurate results.

Adipocytes are the major source of leptin production, and plasma leptin concentrations directly correlate with the amount of total body fat.

Adipocytes are highly specialized cells that play a crucial role in the energy balance of most vertebrates.

Adipocytes convert excess energy to tri-acylglycerol and deposit it during feeding in preparation for periods of food deprivation.

Adipocytes may become enlarged by increased fat storage
